Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention makes it possible to obtain high-quality musical tones using the phoneme piece editing method and the Make IIcM method, especially for the so-called "Shika-1" playing method. This invention relates to a musical tone synthesis device.

(Conventional structure and its problems) In general, what about digital music? Various synthesis methods have been tried as 1 synthesis method, but 1] A conversion 11 in response to the change in the right i in playing style from deer 1 to 1] A conversion 11, discontinuous period 11-? The following methods have been implemented as a solution to the click noise that occurs.

(1) Between two consecutive tones, the output period of the two tones is changed stepwise by linear interpolation or the like.

■ Attenuate the output by one step between two consecutive notes.

In this case, in case (2), when the output cycle ratio processed to Reker 1 is large, click Xfl sound still occurs. There was a drawback that the rise of the subsequent sound of ¥ was fixed, and the gain control did not change unless I added the 1st to 1st roll sections.

(Object of the Invention) The present invention eliminates such conventional drawbacks in the time axis coding synthesis method and provides a musical tone synthesis device that can obtain high-quality musical tones for playing styles J2, so-called Cigar 1, and C. This is what we are trying to provide.

(Structure of the Invention) The present invention provides a synthesized waveform similar to that obtained when gain control is performed without adding the sound of the sound control 1 to the roll part in the ``Shika-1-playing style ++6'', and It is also possible to have a different rise for each pitch,
Furthermore, even for musical tones of the same pitch, it is possible to obtain different rises depending on the playing method. It is configured as follows,
The above will be explained in detail using the drawings.

(Description of Embodiment) FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.
1 is the input section, 2 is the control section, 3 is the table memory section, /1
5 is the phoneme memory section, 5 is the output sofa section, 6 is the A conversion section, and 7 is the word 1 o'clock section.

In this device, after the information regarding the designation of the type of musical instrument and the sweat level is entered into the human power section 1, these information is transmitted to the control R112.
is output to. When the control unit 2 outputs a signal instructing the beginning of the tears, the control unit 2 outputs a signal instructing the beginning of the beginning of the story. Data length, repetition, DA
The information regarding the sampling period is read out, and the phoneme number! is read out from the phoneme memory unit 4 according to this information. After reading out one theta or phoneme group take, it is output to the output buffer section 5 and is also sent from the output buffer section 5 to l) A conversion section 6
An instruction signal indicating the output time period of the digital musical tone signal is output to the output sofa section 5. The outcover sofa part 5 is the control part 2
The digital musical tone signal is outputted to the DA converter 6 in synchronization with the output time period instruction signal from the DA converter 6, and the DA converter 6 converts the digital musical tone signal into an analog musical tone signal. The operations described above are continued until the output instruction signal from the input section stops. In the second step, the tearing part 7 receives a signal regarding the start of opening time and transmits the result of the previous 11 to the control part 2.
output to and start the opening time again.

Next, the characteristic contents of the present invention in this embodiment will be explained.

FIG. 2 shows the time axis envelope of musical tones synthesized according to the present invention.

When the instruction to generate musical sounds to the human power section 1 is executed twice in succession, that is, when the former is set as the first sound and the latter is set as the second sound among the two consecutive sounds from Shika-1 to playing style, Control part 2
When selecting one of the two table memories (Ma and old) that can be used to synthesize the second tone, the predetermined time length 1' related to the continuation plane of the first tone is selected. If it's smaller than ab, that's also Chidel's memory.''
It is assumed that a person selects Chiful Memory +tb. Here, regarding the synthesized sound created by the chiful memories Ma and M+), the length of the musical sound between 1'j-1-ri11.1 is longer than the synthesized sound created by the table memory old 3, which
shall be smaller than the synthesized sound. Musical tones are synthesized through the above steps.

In the description given in , the case where there are two chiffle memories for synthesizing the second tone has been described, but the number is not limited to this, and any number greater than or equal to two may be selected.

(Effects of the Invention) As explained in 1-1, according to the present invention, L/car 1-
To provide a musical tone synthesizer which can solve the problem of clicking and adjusting the sound during the X method without adding a roll part, and can also appropriately vary the rise of the gas cigar 1. There are advantages that can be achieved.

Claims (1)

[Claims] A phoneme memory section that stores phoneme pieces or phoneme groups necessary for synthesizing musical tones with pitches corresponding to the type of musical instrument; and a phoneme memory section that reads out the phoneme pieces or phoneme groups from the phoneme memory section and converts them into digital musical tone signals. a control section for outputting to the output buffer section; an input section for instructing the control section of the type and pitch of musical tones to be output and the start and end of output of the musical tones to be output; a table memory section that stores information regarding the address, data length, number of repetitions, and output cycle in the phoneme memory section of a phoneme piece or group of phonemes to be output to the control section; a buffer section that stores the digital musical tone signal and outputs the digital musical tone signal to a subsequent DA converting section in accordance with information regarding the output cycle; and a DA converter that converts the digital musical tone signal output from the output buffer section into an analog signal. 111 o'clock start signal after the next 111 o'clock start signal and the time until 111 o'clock) and the next a1 o'clock start signal at 11,1''.
